227f9a1c58 - Add vm_paddr_t, a physical address type. This is required for systems
where physical addresses larger than virtual addresses, such as i386s
  with PAE.
- Use this to represent physical addresses in the MI vm system and in the
  i386 pmap code.  This also changes the paddr parameter to d_mmap_t.
- Fix printf formats to handle physical addresses >4G in the i386 memory
  detection code, and due to kvtop returning vm_paddr_t instead of u_long.

Note that this is a name change only; vm_paddr_t is still the same as
vm_offset_t on all currently supported platforms.

c2fae87169 Don't call sysbeep() in sc_bell() if either duration or pitch is zero.
Otherwise sysbeep() makes an annoying clicking sound on some systems.
'kbdcontrol -b off' just sets the duration and pitch to zero, it doesn't
set the QUIET_BELL flag.

7ac40f5f59 Gigacommit to improve device-driver source compatibility between
branches:

Initialize struct cdevsw using C99 sparse initializtion and remove
all initializations to default values.

This patch is automatically generated and has been tested by compiling
LINT with all the fields in struct cdevsw in reverse order on alpha,
sparc64 and i386.

03ab197379 When DDB is in the kernel, unlock VTY switching so that we
don't end up freezing the box.  This makes VTY locking useless
in the DDB case but a box which is supposed to be physically
secure shouldn't compile DDB anyway.

07159f9c56 Cleanup of the d_mmap_t interface.
- Get rid of the useless atop() / pmap_phys_address() detour.  The
  device mmap handlers must now give back the physical address
  without atop()'ing it.
- Don't borrow the physical address of the mapping in the returned
  int.  Now we properly pass a vm_offset_t * and expect it to be
  filled by the mmap handler when the mapping was successful.  The
  mmap handler must now return 0 when successful, any other value
  is considered as an error.  Previously, returning -1 was the only
  way to fail.  This change thus accidentally fixes some devices
  which were bogusly returning errno constants which would have been
  considered as addresses by the device pager.
- Garbage collect the poorly named pmap_phys_address() now that it's
  no longer used.
- Convert all the d_mmap_t consumers to the new API.

I'm still not sure wheter we need a __FreeBSD_version bump for this,
since and we didn't guarantee API/ABI stability until 5.1-RELEASE.

263444cfbf Change the console interface to pass a "struct consdev *" instead of a
dev_t to the method functions.

The dev_t can still be found at struct consdev *->cn_dev.

Add a void *cn_arg element to struct consdev which the drivers can use
for retrieving their softc.

47e40520dd Do not try to work around ``poor (un)sign extension code''
creation by GCC-2.6.3.  Casting pointers to unsigned char
to volatile pointers to unsigned char seemed to produce
better results on the ia32 architecture with old versions
of GCC.
The current FreeBSD system compiler GCC-3.2.1 emits
better sign extension code for non-volatile variables:

volatile char c;
int i = c;

is compiled to:
...
movb	-1(%ebp), %al
movbsl	%al, %eax
movl	%eax, -8(%ebp)
...

char c;
int i = c;

is compiled to:
...
movbsl	-1(%ebp), %eax
movl	%eax, -8(%ebp)
...

The same holds for zero-extension of dereferenced pointers
to volatile unsigned char.
When compiled on alpha or sparc64, the code produced for the
two examples above does not differ.

f457830b8e de-count schistory.c. The handling of NSC was rather bogus here and was
little more than a place holder, because nothing actually counted the
number of 'sc' units to compare it against NSC.  A bit more work here
is needed so that the scaling of SC_MAX_HISTORY_SIZE and extra_history_size
goes up when more sc units are added.  But, it does not appear that we can
have more than one console yet, so it does not seem particularly urgent.

ce907d4246 Add a VT_LOCKSWITCH ioctl that disallows vty switching. Something
like this can be emulated by VT_SETMODEing to VT_PROCESS and never
releasing the vty, but this has a number of problems, most notably
that a process must stay resident for the lock to be in effect.

hw.syscons.saver.keybonly: used to specify that only input is to

There should probably also be an ioctl for this, we'll do that later.

44731cab3b Change the suser() API to take advantage of td_ucred as well as do a
general cleanup of the API.  The entire API now consists of two functions
similar to the pre-KSE API.  The suser() function takes a thread pointer
as its only argument.  The td_ucred member of this thread must be valid
so the only valid thread pointers are curthread and a few kernel threads
such as thread0.  The suser_cred() function takes a pointer to a struct
ucred as its first argument and an integer flag as its second argument.
The flag is currently only used for the PRISON_ROOT flag.

f591779bb5 Lock struct pgrp, session and sigio.
New locks are:

- pgrpsess_lock which locks the whole pgrps and sessions,
- pg_mtx which protects the pgrp members, and
- s_mtx which protects the session members.

Please refer to sys/proc.h for the coverage of these locks.

Changes on the pgrp/session interface:

- pgfind() needs the pgrpsess_lock held.

- The caller of enterpgrp() is responsible to allocate a new pgrp and
  session.

- Call enterthispgrp() in order to enter an existing pgrp.

- pgsignal() requires a pgrp lock held.

 - Remove obsolete `#ifdef DEV_APM' related code.
